Results for the year ended 31 December 2017

Modern Water plc (AIM:MWG), the owner of leading technologies for water and wastewater treatment and for the monitoring of water quality, announces that its results for the year ended 31 December 2017, whilst broadly in line with the prior year numbers in terms of (i) revenue and (ii) operating profit prior to exceptional items, are expected to be below market expectations, primarily due to a shortfall in anticipated revenue originating from its Monitoring Division in China following its change in 2017 of its product sales model from exclusive distributor to multiple channels. The Company is pleased to report that as a result of the change of distribution model, the Monitoring Division's sales in January and February 2018 are 17% ahead of the same period in 2017, as well as with a substantially stronger order book.

Modern Water anticipates releasing its results by no later than 31 March 2018.
